【问题描述】：

SmartConnect 方法抛出错误 requests.exceptions.SSLError:[Errno8]_ssl.c ？如何解决它

我正在使用 pyvmomi-5.5.0.2014.1.1 包来自动化 VMWare 服务器。通过 VMware ESXi 5.1 使用相同的凭据，我能够连接到服务器但是在尝试通过代码时


    from pyVim import connect
    def connect_to_server(self, server=None, user=None, pwd=None, port=None):
    if server is None:
        server = _config_values("general", "host")
    if user is None:
        user = _config_values("general", "username")
    if pwd is None:
        pwd = _config_values("general", "password")
    if port is None:
        port = _config_values("general", "port")
    self._server = server
    self._user = user
    self._password = pwd
    self._port = int(port)
    try:
        service_instance = connect.SmartConnect("http", self._server,  self._port, self._user, self._password)
    except ConfigParseError:
        pass

它抛出错误 insecureplatformwarning 并建议 urllib3 url 。按照页面中的建议安装软件包 pyopenssl ndg-httpsclient pyasn1 然后添加


    import urllib3.contrib.pyopenssl
    urllib3.contrib.pyopenssl.inject_into_urllib3()

现在在上面的代码中我得到了错误：

<pre><code>

这对我有用http://www.errr-online.com/index.php/2015/05/09/how-to-fix-ssl-issues-with-pyvmomi-and-python-2-7-9/

import requests
requests.packages.urllib3.disable_warnings()

import ssl

try:
    _create_unverified_https_context = ssl._create_unverified_context
except AttributeError:
    # Legacy Python that doesn't verify HTTPS certificates by default
    pass
else:
     # Handle target environment that doesn't support HTTPS verification
    ssl._create_default_https_context = _create_unverified_https_context

我只是将它添加到我的脚本中。

【讨论】：

谢谢，已经尝试过类似的解决方案，我在这个或类似的解决方案中得到的问题是 _create_unverified_context 变量抛出未定义变量错误，即使已经导入 ssl 然后使用 ssl._create_unverified_context

【解决方案2】：

对于 Python 3.4，只有 hevel 答案对我有用。这是一个略短的版本：

sslContext = ssl.create_default_context(purpose=ssl.Purpose.CLIENT_AUTH)
sslContext.verify_mode = ssl.CERT_NONE
si = SmartConnect(host=host,user=username,pwd=password,sslContext=sslContext)

我在 Python 2.x 上成功地使用了 Michaels 解决方案和 pyvmomi，直到今天我决定将我的 pyvmomi 库迁移到 Python 3。在 Python 3.4 中，由于 ssl 错误略有不同，它已停止工作：

ssl.SSLError: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed...

从逆向工程中，我得出了与 hevel 相同的结论。事后看来，我希望我刚刚回到 StackOverflow 在这里仔细检查答案。

【解决方案3】：

这适用于 python2.7.9

sslContext = ssl.create_default_context()
sslContext.check_hostname = False
sslContext.verify_mode = ssl.CERT_NONE
si = SmartConnect(host=host,user=username,pwd=password,sslContext=sslContext)

【解决方案4】：

下面的代码让我使用 python 3.7 版和 pyvmomi 6.7.0.2018.9 版连接到运行 ESXi6.5 的主机

from pyVim import connect
import ssl
def login():
    si = connect.ConnectNoSSL(host='192.168.1.123', user='root', pwd='password')
    print(si.content)

if __name__ == '__main__':
    login()

【解决方案5】：

我用的是python3.6，下面给出一个完整的例子。可以正常工作。

#!/usr/bin/env python3.6
# encoding: utf-8

from pyVim import connect
import ssl


def login():
    ssl_context = ssl.create_default_context(purpose=ssl.Purpose.CLIENT_AUTH)
    ssl_context.verify_mode = ssl.CERT_NONE
    si = connect.SmartConnect(host='192.168.0.1', user='root', pwd='password',
                              sslContext=ssl_context)
    print(si)
    print('If you got here, you authenticted into vCenter.')


if __name__ == '__main__':
    login()
